YouTube creator Morten has posted a video in which he attempts to populate a breakout board for the Sandia Technologies grain-of-rice sized ARM Cortex-M0+ microcontroller.
The device went on sale in March of this year, but due to its diminutive size and similarity to other packages such as a 32-pin TQFP, it is not straightforward to solder.
The video shows Morten creating a unique footprint for the device in KiCad and then soldering it by hand to a blank PCB, with all of the I/O broken out to a header to enable simple testing and inspection.
The finished board is then used to create a simple I2C-based thermometer.
The video is embedded in an article on Hackaday, accompanied by a written summary.
